NI 9516 Operating Instructions and Specifications
System Connection
The NI 9516 has two connectors, a 15-pin DSUB drive interface
connector and a 20-pin MDR feedback connector. The 15-pin
DSUB includes command signals for interfacing with servo
amplifiers or drives, a 0 to 30 V general-purpose digital input line,
and a 19 to 30 V input for power connection. Refer to Table 1 for
the DSUB connector pin assignments.
Note
The remainder of this document does not
distinguish between drives and amplifiers. All
references to drives also apply to amplifiers.
The 20-pin MDR connector includes dual incremental encoder
feedback inputs, a +5 V output for encoder power, home, limit, and
position compare inputs, an output for position compare, an
additional 19 to 30 V input for power connection, and an additional
0 to 30 V general-purpose digital input line. Refer to Figure 2 for
the MDR connector pin assignments.
Note
The NI 9516 requires an external power supply.
You can connect the external power supply to the V
sup
input provided on the DSUB or MDR connector. Do not
connect more than one external power supply to the
module.
